Question

Carlos operates a helicopter. Carlos decides to measure the rotational velocity of the helicopter blades. What would be an appropriate unit for Carlos's purpose? ​
a) ​meters/second
b) degrees/square second
c) degrees/second
d) meters/square second
​​

Answer 1

Answer:

The correct option is C.  

Step-by-step explanation:

Given that Carlos operates a helicopter. Carlos decides to measure the rotational velocity of the helicopter blades. we have to find the appropriate unit for Carlos's purpose.

The angular velocity ω is the rate of change of angle with respect to time,

The formula to find the rotational velocity is

$\text{Rotational velocity}=\frac{d\phi}{dt}$

Angle measure in radians or degrees and time in second.

Hence, the appropriate unit for Carlos's purpose is degrees per second.

The correct option is C.
